Background: Heatstroke is one of the most serious heat-related illnesses. However, establishing public policies to prevent heatstroke remains a challenge. This study aimed to investigate the most relevant climate elements and their warning criteria to prevent outdoor heatstroke (OHS). Methods: We investigated heatstroke patients from five major hospitals in Daegu metropolitan city, Korea, from June 1 to August 31, 2011 to 2016. We also collected the corresponding regional climate data from Korea Meteorological Administration. We analyzed the relationship between the climate elements and OHS occurrence by logistic regression. Results: Of 70 patients who had heatstroke, 45 (64.3%) experienced it while outdoors. Considering all climate elements, only mean heat index (MHI) was related with OHS occurrence (p=0.019). Therefore, the higher the MHI, the higher the risk for OHS (adjusted odds ratio, 1.824; 95% confidence interval, 1.102-3.017). The most suitable cutoff point for MHI by Youden's index was $30.0^{\circ}C$ (sensitivity, 77.4%; specificity, 73.7%). Conclusion: Among the climate elements, MHI was significantly associated with OHS occurrence. The optimal MHI cutoff point for OHS prevention was $30.0^{\circ}C$.

Purpose: To evaluate the severity of trauma, many scoring systems and predictive models have been presented. The quick Sequential Organ Failure Assessment (qSOFA) is a simple scoring system based on vital signs, and we expect it to be easier to apply to trauma patients than other trauma assessment tools. Methods: This study was a cross-sectional study of trauma patients who visited the emergency department of Jeju National University Hospital. We excluded patients under the age of 18 years and unknown outcomes. We calculated the qSOFA, the Modified Early Warning Score (mEWS), Revised Trauma Score (RTS), and Injury Severity Score (ISS) based on patients' initial vital signs and assessments performed in the emergency department (ED). The primary outcome was mortality within 14 days of trauma. We analyzed qSOFA scores using multivariate logistic regression analysis and compared the predictive accuracy of these scoring systems using the area under the receiver operating characteristic curve (AUROC). Results: In total, 27,764 patients were analyzed. In the multivariate logistic regression analysis of the qSOFA, the adjusted odds ratios with 95% confidence interval (CI) for mortality relative to a qSOFA score of 0 were 27.82 (13.63-56.79) for a qSOFA score of 1, 373.31 (183.47-759.57) for a qSOFA score of 2, and 494.07 (143.75-1698.15) for a qSOFA score of 3. In the receiver operating characteristic (ROC) curve analysis for the qSOFA, mEWS, ISS, and RTS in predicting the outcomes, for mortality, the AUROC for the qSOFA (AUROC [95% CI]; 0.912 [0.871-0.952]) was significantly greater than those for the ISS (0.700 [0.608-0.793]) and RTS (0.160 [0.108-0.211]). Conclusions: The qSOFA was useful for predicting the prognosis of trauma patients evaluated in the ED.
Purpose: In Korea, most abdominal penetrating wounds are caused by stab wounds rather than gun-shot wounds. However, not many studies have been performed on stab injuries and their epidemiologic characteristics. Disagreements of opinions of obligatory surgical exploration and conservative treatment exist, and this subject is still being debated. Therefore, the authors studied the epidemiologic characteristics of abdominal stab wound patients visiting the emergency department and reviewed the proportion of patients that received nontherapeutic surgery and conservative treatment. Methods: This study included patients visiting the emergency department with abdominal stab wounds. A retrospective chart review was done on the abdominal stab wound patients. Sex, age, cause of injury, location of wound, initial vital signs, operation results, injured organs and CT & LWE results were reviewed. Results: The median age of the 121 patients was 40.9 years, of these patients, 88 were males, of which 52 (43.0%) were drunken. Of the patients that received non-therapeutic operations, only 3 patients (15.0%) were drunken, significantly lower than the therapeutic operation group. For the location of the wound, most patients were injured in the right and left upper quadrants, 27 patients each. The most common injured organ was the small bowel; 13 patients were injured in the small bowel. With abdominal CT scans and local wound explorations together, the results exhibited a sensitivity of 97%, a specificity of 44%, a positive predictive value of 56%, and a negative predictive value of 95%. Conclusion: In our study, the sensitivity was 97% when CT & LWE were performed together; thus we can conclude that CT and LWE can be used together to select the treatment method. Although in our study, the surgical indications in abdominal stab wound patients is not sufficient, our results showed a higher rate of nontherapeutic surgery compared to previous studies. Therefore, more research is needed to prevent unnecessary laparotomies in hemodynamically-stable patients without symptoms.
Purpose: To evaluate the association between neutrophil-to-lymphocyte ratio (NLR) and occurrence of aspiration pneumonia in drug intoxication (DI) patients in the emergency department (ED) and to evaluate the relationship between NLR and length of hospital admission/intensive care unit (ICU) admission Methods: A total of 466 patients diagnosed with DI in the ED from January 2016 to December 2017 were included in the analysis. The clinical and laboratory results, including NLR, were evaluated as variables. NLR was calculated as the absolute neutrophil count/absolute lymphocyte count. To evaluate the prognosis of DI, data on the development of aspiration pneumonia were obtained. Also, we evaluated the relationship between NLR and length of hospital admission and between NLR and length of ICU admission. Statistically, multivariate logistic regression analyses, receiver-operating characteristic (ROC) curve analysis, and Pearson's correlation (${\rho}$) were performed. Results: Among the 466 DI patients, 86 (18.5%) developed aspiration pneumonia. Multivariate logistic regression analysis revealed NLR as an independent factor in predicting aspiration pneumonia (odds ratio, 1.7; p=0.001). NLR showed excellent predictive performance for aspiration pneumonia (areas under the ROC curves, 0.815; cut-off value, 3.47; p<0.001) with a sensitivity of 86.0% and a specificity of 72.6%. No correlations between NLR and length of hospital admission (${\rho}=0.195$) and between NLR and length of ICU admission (${\rho}=0.092$) were observed. Conclusion: The NLR is a simple and effective marker for predicting the occurrence of aspiration pneumonia in DI patients. Emergency physicians should be alert for aspiration pneumonia in DI patients with high NLR value (>3.47).
Purpose: The aim of this study was to evaluate the characteristics and the prognostic factors of carbamate poisoned patients who visited emergency departments. Methods: From August 2005 to July 2006, we investigated the demographic feature, dose of exposure, time of exposure, alcohol intake, route of exposure, reason of exposure, site of exposure, pre-existing medical condition, time from exposure to emergency department (ED), transfer from other hospitals, vital sign at ED arrival, symptom or sign at ED arrival, and result of care of the patients who visited the ED of thirty-eight hospitals in Korea. According to the result of care, we divided the patients into two groups, the survival and the dead. To evaluated the prognostic factors, we calculated the odds ratio of each factor for the survival. Results: Among the sixty-eight patients, fifty-five patients (80.9%) were survival and thirteen patients (19.1%) were dead. The patients in the dead were older than the patients in the survival. The Glasgow coma scale (GCS) of the patients in the dead was lower than the GCS in the survival. The odds ratio of the GCS at ED arrival for the survival was 1.58 (95% CI; 1.23-2.05). Other factors showed no statistical significances. Conclusion: The GCS at emergency department arrival was the prognosis factor of the carbamate poisoned patients who visited emergency departments. If the carbamate poisoned patients showed altered mentalities, they should be provided intensive care, immediately.
Objective: This study examined the predictive factors for prolonged length of stays of adult patients with acute appendicitis (AA) in an emergency department (ED). Methods: This was a retrospectively clinical study including patients in an ED. All patients were diagnosed from the clinical symptoms and a typical physical examination, and had undergone a computed tomography (CT) evaluation on the ED visiting date. All data were collected from the electrical medical records. The clinical parameters analyzed were the laboratory data, including the white blood cell count with differential values, C-reactive protein (CRP) level, initial vital signs, duration of admission, coexisting perforation of the appendix in the CT findings. The relationship between the clinical parameters and length of stay was assessed. Results: A total of 547 patients with AA were enrolled in this study. Among them, there were 270 male patients with a mean age of $40.7{\pm}15.8years$. The baseline characteristics, initial clinical features, laboratory, and imaging studies results of 129 patients in the prolonged length of stay (pLOS) group, and 418 patients of the non-pLOS group in AA were compared. Multivariable logistic regression analysis revealed the predictive factors related to pLOS in AA to be as follows: age 40 years or older, body temperature over $37.3^{\circ}C$, CRP level greater than 5.0 mg/dL, and evidence of perforation in CT findings (P<0.001). Conclusion: If we check age, fever, CRP level and find evidence of perforation, it might be helpful for predicting the increasing period of length of hospital stay for patients with AA in ED.
Purpose: The purpose of this study was to investigate the relationship between patients with a neuropsychiatric history and features of their suicide attempt, in order to analyze the risk associated with psychiatrist prescribed drugs Methods: We retrospectively investigated cases of intentional overdose drug ingestion in patients greater than 14 years of age who visited OO emergency medical center between January 1, 2008 and July 31, 2010. We evaluated patient medical records to ascertain their age, sex, neuropsychiatric history, and components of ingested intoxicant. Information regarding any suicide reattempt was obtained after discharge through follow up telephone survey. SPSS version 13.0 was used for statistical analysis. Fisher's exact test was performed with p<0.05 considered statistically significant. Results: Ninety-six of 209 patients (46%) had a past history of psychological problems. Among those 96 patients with a history of psychological problems, 46(48%) used an overdose of the medicine prescribed by their psychologist in order to attempt suicide. However, for patients without a history of psychological problems, intoxication by neuropsychiatric drugs was insignificant. Neuropsychiatric patients required greater follow up care after discharge and exhibited significantly more suicide reattempts. Conclusion: This study revealed that patients sometimes use the medicine prescribed by their psychologist to attempt suicide. Therefore, an exhaustive plan to control the medicines prescribed to psychiatric patients should be established.
Purpose: This study was conducted to investigate the frequency and clinical characteristics of anaphylaxis patients who are registered inaccurately with other disease codes. Methods: Study subjects presenting at the emergency department (ED) were retrospectively collected using disease codes to search for anaphylaxis patients in a previous studies. The study group was divided into an accurate and inaccurate group according to whether disease codes were accurately registered as anaphylaxis codes. Results: Among 266 anaphylaxis patients, 144 patients (54%) received inaccurate codes. Cancer was the most common comorbidity, and the radio-contrast media was the most common cause of anaphylaxis in the accurate group. Cutaneous and respiratory symptoms manifested more frequently in the inaccurate group, while cardiovascular and neurological symptoms were more frequent in the accurate group. Blood pressure was lower, and shock and non-alert consciousness were more common in the accurate group. Administration of intravenous fluid and epinephrine use were more frequent in the accurate group. Anaphylaxis patients with a history of cancer, shock, and epinephrine use were more likely to be registered as anaphylaxis codes accurately, but patients with respiratory symptoms were more likely to be registered with other disease codes. Conclusion: In cases of anaphylaxis, the frequency of inaccurately registered disease codes was higher than that of accurately registered codes. Anaphylaxis patients who were not treated with epinephrine at the ED who did not have a history of cancer, but had respiratory symptoms were at increased risk of being registered with disease codes other than anaphylaxis codes.
Purpose: Many patients are injured by trauma. And some of them expire due to severity of trauma. Various scoring systems have been introduced in grading severity and predicting mortality of trauma patients. This study is to evaluation the usefulness of factors for determining the severity and predicting the prognosis of the trauma victims. Methods: Data on the patients who visited our Emergency departments from January 2010 to December 2011 were retrospectively reviewed using electronic medical records. The patients were activated severe trauma team calling system. The patients were categorized as survivors and non-survivors. Univariated associations were calculated, and a multiple logistic regression analysis was used to determine variables associated with hospital mortality. Results: Two hundred sixty two(262) patients were enrolled, and the mortality rate was 25.6%. By multivariate analysis, lower respiration rate, lower Glasgow Coma Score, higher International Normalized Ratio and emergency transfusion within 6 hours were expected as severity and prognosis predict factors (each of odds ratio were 24.907, 14.282, 2.667 and 16.144). Conclusion: As predict factors, respiration rate, Glasgow Coma Score, International Normalized Ratio and emergency transfusion, are useful determining the severity and predicting prognosis of trauma victims.
